Background

The drum screen is a machine widely applied in the sorting technology, controls the sorting of garbage by controlling the particle size of particles, and has high sorting precision. The drum body of the drum screen is generally divided into a plurality of sections, the screen holes are arranged from small to large according to specific conditions, and the aperture of each section of screen hole is the same. The drum screen mainly comprises a motor, a speed reducer, a drum device, a frame, a sealing cover and a feed inlet and a discharge outlet. The basic structure of the drum screen is as follows: the roller device is obliquely arranged on the frame. The motor is connected with the roller device through the speed reducer and the shaft coupling, and drives the roller device to rotate around the axis of the roller device. After the materials enter the roller device, the materials on the screen surface are overturned and rolled due to the inclination and rotation of the roller device, so that the qualified materials (undersize products) are discharged through a discharge hole at the bottom of the rear end of the roller, and the unqualified materials (oversize products) are discharged through a discharge hole at the tail part of the roller. Because the material is upset, the roll in the cylinder, make the material of card in the sieve mesh can be popped out, prevent that the sieve mesh from blockking up. The principle and structure of the roller sand screening machine, the roller screening machine and the roller screen are almost the same, and the difference exists in people's understanding and calling. Because the mesh size is certain, when the material is sieved, the material still contains the screening finished product of multiple specifications, and in some places with high screening requirements, further sorting is needed according to the granularity.
